Hello!, I have texturized. Instead of an explanation of the process, I am going to list the new things that I have done, they will not be in chronological order:
-Texturize the teeth, tongue and eyes, nothing new compared to the body, just say that I take advantage of a free space that I had left in one of the textures of the body to put the tongue and teeth, so I get the most out of it and being small things did not need so much space, with the eyes if you create new images and it is better that you have their images only for eyes
-Both Leah and all the NPC`s of Stardew Valley have several images with different expressions that change depending on the context, one that Leah has is her blushing, so I duplicated the texture of the face and added that blush, in the material are the 2 images and thanks to a node it can be alternated, at the moment it is cumbersome since it requires selecting the body and going to the Shading section to change this, but there is the possibility of joining that together with other things in the same section together and more accessible , I have not investigated much but I have seen models that people have made and I know that it is possible
-Delete the Ambient Occlusion node, actually as I had it on it didn't do anything
-I made more tweaks to the body mesh
The next step is to model the hair
